Wideband Units Enable Multiplexing From 0.5 To 40.0 GHz

A series of contiguous-channel wideband multiplexers is available for applications over 0.5 to 40.0 GHz. These multiplexers allow the selection of any combination of 12 standard crossover frequencies from 1 to 34 GHz. With this design flexibility, multiplexing is easily achieved for the most popular electronic-warfare bands from0.5 to 40.0 GHz. Available crossover frequencies are: 1,2, 4, 6,8,19, 12, 14, 18, 20, 26, and 34 GHz. Crossover regions are within +4 percent of the center frequency to a maxium of +5 percent at 2 GHz and below. The multiplexer exhibits crossover insertion loss to 4.5 dB (5 dB below 2 GHz). It exhibits passband insertion loss to 1.0 dB from DC to 18 GHz and to 1.5 dB from 18 to 40 GHz. The multiplexer provides a common-port VSWR to 2.0:1 maxium from DC to 18 GHz and 2.5:1 maximum from 18 to 40 GHz. Selectivity is 60 dB minimum within +15 percent of the center frequency and at the band edges when specified. The 0.400-in.-high multiplexers operate from -54 to +85C. Band-edge rejection options are available.
